guys cie dont expect the candidates to be engineers and wknow what is used to reinforce concrete... i think its just common sense....
they mentioned that the expansion of steel is the same as concrete, and aluminium isnt, so if u use aluminium it would expand at a different rate than concrete, and it would cause problemes to the structure.
and plus... its known that steel is used to reinforce concrete :P  ;D

agree

After all is said and done, more is said than done.

By the time a man realizes that maybe his father was right, he usually has a son who thinks he’s wrong.

since 21 hours have past, i'm sure by know everyone on the planet have taken the test

so how was it
By the way what was the mass and the fraction on the energy question


i got 1/8 for the fraction thing....and wat did you get for pressure question when they asked wat the pressure would be if the area was doubled? ....i halved the pressure....and the diode i said D  ::)



yea so did i get the same answer. hope its right?
